similar to: probit with sample selection error?

Is anyone aware of an R procedure similar to STATA's "heckprob" procedure? "Heckprob" fits maximum likelihood probit models correcting for sample selection bias. Thanks, Richard Saba Department of Economics Auburn University Email: sabaric@auburn.edu [[alternative HTML version deleted]]

Deae R helpers, the problem I'm facing today is related to the manipulation of a string. The string is coming from a a porosimeter, whose control is under a complicate set-up of two computers One (running on DOS) is controlling directly the hardware, while the other (running on win XP) which process the data is connected to the first one via serial. I get the data from this last computer.

Hi, I have a matrix of say 1024x1024 and I want to look at it in chunks. That is I'd like to divide into a series of submatrices of order 2x2. | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | | 1 2 3 4 5 6 7 8 ... | ... So the first submatrix would be | 1 2 | | 1 2 | the second one would be | 3 4 | | 3 4 | and so on. That is I want the matrix to be evenly divided

Hello, my name is Torsten Koffler, a Senior Software Engineer at Nero AG (Germany). I am the manager for Windows Quality Online Services (Winqual) issues in our company.

Colleagues, I am using R to assemble RTF documents (which are plain text). I need to embed a JPEG graphic that was created with R. I presume that the steps need to be: a. read the file into R b. convert the object to HEX format c. write the converted object to a textfile. If I read the file into R using readLines, I get the following (only the first 5 lines shown): > >

Dear R users, I have a problem. I would like to solve the following: I have pL = 1/(1+e^(-b0+b1)) pM = 1/(1+e^(-b0)) pH = 1/(1+e^(-b0-b1)) My target function is TF= mean(pL,pM,pH) which must equal 0.5% My non-linear constraint is nl.Const = 1-(pM/pH), which must equal 20%, and would like the values of both b0 and b1 where these conditions are met. I have searched widely for an answer,

Buenos días: Por favor, ¿alguien podría crear un script de r con este código que envío e intentar paquetizarlo?. Yo siempre lo conseguía, pero con la versión actual de R (3.1.0), una vez generado el zip del paquete y cargado desde la RGui, no me detecta la existencia del environment que creé (.Ch.env). Es como si ahora el pkt sólo pudiera estar integrado (a efectos prácticos) por funciones, sin

Does ActiveRecord.connection.execute(string) perform any modifications on the given string? If so, what quoting do I need to add? Here''s why: I''m trying to use execute(string) to load a stored procedure. I can hand-load the procedure without error (i.e. via dbconsole), but when I call the function below, it throws the error: ==== ActiveRecord::StatementInvalid: Mysql::Error:

Queridos, Me apunté a esta lista de correo con el objetivo de avanzar en mi proceso de aprendizaje con R y R-Commander. Mis limitados conocimientos me hacen ver que este no es el foro que necesito, su nivel es demasiado avanzado para mí. Si me podeis orientar para estar en el foro adecuado que sería tener oportunidad de comentar problemas de los primeros pasos con R y R-Commander os lo

Hola Eva. Me alegro de que hayas resuelto el problema! De todas formas, no tendrá algo que ver con los problemas de "globalización" de las variables que ya has tenido en .ChrL.env (hace un par de años, creo recordar)?.

Congratulations Eva I have been following this thread loosely. Well in the sense that I really didn't understand what was going on but hopefully thinking that I could learn something from it. Your approach to your particular setup didn't pay any attention to the heed by Duncan. So you hard headed (pig headed, stubborn as a monkey) wanted it to be your way. Now I guess you accidentally

Hi everybody I have a very big problem: With R 3.0.2 I could construct the package for this code: if (exists('.ChrL.env') == TRUE) {   rm(.ChrL.env) } .ChrL.env <- new.env() .ChrL.env$lGlo <- list() .ChrL.env$bStarted <- FALSE CheckGloCreated <- function() {   if (.ChrL.env$bStarted == TRUE) {     stop("Data structures were already initialized.", call.=FALSE)

See description in the attached patch. -------------- next part -------------- This quick hack adds primitive support of UTF-8 as a server 'character set' to Samba 2.0.7. All file, share and user names are stored on server in UTF-8, and translated into client code page (not UCS2) on the fly. Additionally, server string conversion is added. Tested with Chinese and Russian Windows clients.
